Lift wells must be completely enclosed by non-combustible materials to prevent the spread of fire and smoke.
Systems must feature automated load-weighing devices that prevent the car from moving if the rated capacity is exceeded, accompanied by an audible warning. 3. Major Safety Advancements in the 2021 Standard
The Code is divided into a logical structure to guide designers and engineers through the various types of vertical transportation equipment. As outlined in an addendum to the 2012 edition (which the 2021 edition updates and expands), the core technical specifications are typically categorized into distinct parts, each addressing a different type of equipment: Lift wells must be completely enclosed by non-combustible
Sensors must immediately halt the escalator if foreign objects become wedged between the steps and the combplate.
While the ordinance is legal text, the code of practice is appended as a technical guidance document. The e-Legislation portal often hosts the most current version with errata. Major Safety Advancements in the 2021 Standard The
Escalators are prone to sudden deceleration or directional reversal failures under heavy loads. The code mandates auxiliary braking systems that engage immediately if the drive chain snaps or if the speed exceeds a designated percentage of the rated speed. 4. Maintenance, Inspection, and Testing Framework
Components like safety gears, door locks, and buffers must carry verified certificates from recognized independent testing bodies. The e-Legislation portal often hosts the most current
Multi-beam photoelectric sensors (light curtains) are mandatory to detect obstructions across the full height of the door opening.
General introductions, terminology, references, and common symbols/abbreviations.
Landing doors must be openable from the outside using a specialized triangle key during rescue operations.
The is a vital regulatory and technical standard that ensures the safety, reliability, and efficiency of vertical and horizontal transit systems in modern buildings. Primarily published by engineering and building regulatory authorities—such as Hong Kong's Electrical and Mechanical Services Department (EMSD) or similar international safety bodies—the 2021 edition updates previous standards to integrate advanced technologies, new material requirements, and stricter safety protocols.
